A new CNET online course promises to teach you how to detect and defeat the bane of most Windows users' existence: adware and spyware.

In this course, you'll learn the best defenses against spyware and adware; how to defeat hard-to-remove spyware; where to find free security software and security sites that help keep your computer safe.

The class, conducted by IT support professional Seamus Condron, runs for two weeks and invites (though does not require) user participation via the "classroom discussion blog." It starts today, though you can enroll at any time. — Rick Broida
